“Postman theorised that the printed page and the spread of literacy extended and changed (in fact he said “invented”) childhood. Learning abstract knowledge takes time, though the peasant kids were still taking part in work-life out in the real world”
Quote; "Precocious Puberty Triggers
While there’s no direct evidence EMF exposure during childhood can trigger early puberty, one animal study21 did find Wi-Fi and cell phone radiation during pregnancy increased the risk of early puberty in the offspring.
So, it’s possible that generational effects are at play, and/or that this susceptibility is worsened by other environmental factors such as diet, lack of exercise, obesity, stress and exposure to endocrine-disrupting chemicals and foods high in estrogen.
Without a clear cause, it’s difficult to prescribe a remedy. But I believe it’s safe to say that parents would be wise to pay close attention to what their children are doing and being exposed to — pandemic or not" https://forum.5filters.info/c/covid/9
Quote; "Investing heavily in school computers and classroom technology does not improve pupils’ performance, says a global study from the OECD.
The think tank says frequent use of computers in schools is more likely to be associated with lower results.
The OECD’s education director Andreas Schleicher says school technology had raised “too many false hopes”.
Tom Bennett, the government’s expert on pupil behaviour, said teachers had been “dazzled” by school computers.
The report from the Organisation for Economic Co-operation and Development examines the impact of school technology on international test results, such as the Pisa tests taken in more than 70 countries and tests measuring digital skills.
It says education systems which have invested heavily in information and communications technology have seen “no noticeable improvement” in Pisa test results for reading, mathematics or science.
“If you look at the best-performing education systems, such as those in East Asia, they’ve been very cautious about using technology in their classrooms,” said Mr Schleicher.
“Those students who use tablets and computers very often tend to do worse than those who use them moderately.”" https://www.bbc.com/news/business-34174796
Quote; "Allowing students to use computers and the internet in classrooms substantially harms their results, a study has found.
The paper published by the Massachusetts Institute of Technology found that students barred from using laptops or digital devices in lectures and seminars did better in their exams than those allowed to use computers and access the internet.
The researchers suggested that removing laptops and iPads from classes was the equivalent of improving the quality of teaching.
The study divided 726 undergraduates randomly into three groups in the 2014-15 and 2015-16 academic years. The control group’s classrooms were “technology-free,” meaning students were not allowed to use laptops or tablets at their desk. Another group was allowed to use computers and other devices, and the third group had restricted access to tablets.
“The results from our randomised experiment suggest that computer devices have a substantial negative effect on academic performance,” the researchers concluded, suggesting that the distraction of an electronic device complete with internet access outweighed their use for note-taking or research during lessons.
The research had an unusual twist: the students involved were studying at the West Point academy in the US, where cadets are ruthlessly ranked by exam results, meaning they were motivated to perform well and may have been more disciplined than typical undergraduates.
But even for the cream of the US army’s future crop, the lure of the digital world appears to have been too much, and exam performance after a full course of studying economics was lower among those in classes allowed to use devices." https://www.theguardian.com/education/2016/may/11/students-who-use-digital-devices-in-class-perform-worse-in-exams
